Uranium is a chemical element; it has symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays, usually by emitting an alpha particle.
Uses. Uranium is a very important element because it provides us with nuclear fuel used to generate electricity in nuclear power stations. It is also the major material from which other synthetic transuranium elements are made. Naturally occurring uranium consists of 99% uranium-238 and 1% uranium-235.
Uranium is a weakly radioactive element discovered in 1789 by Martin Heinrich Klaproth. It is widely used to fuel nuclear power plants and to make high density penetrators. Atomic bomb is also made using Uranium.
6 gru 2023 · Uranium, a metallic chemical element found in the periodic table with atomic number 92 and denoted by the symbol U, displays a silvery-white appearance. Each uranium atom is characterized by 92 protons and 92 electrons, including 6 valence electrons. Notably, uranium boasts the highest atomic weight among naturally occurring elements.
- Uranium is a heavy, silvery-white metal that is part of the actinide series in the periodic table. - It plays a crucial role in the field of nuclear energy, being a primary fuel used in nuclear reactors. - As a metal, it is solid at room temperature, with a high density and poor electrical conductivity compared to other metals.
8 kwi 2014 · Uranium, with symbol "U" and atomic number 92 on the periodic table, is a radioactive element with several notable isotopes found in group 3 of the periodic table. It belongs to period 7, which means that its seventh energy level contains electrons.
